ポケットに入る万年筆用一本差しペンケース「dünn one pencover」様々な万年筆に入れてみました。ペンカバー、ペンシースとしてプレゼントに添えてもGood!

``dünn one pencover'', a single pen case for fountain pens that fits in your pocket, I tried putting it in various fountain pens. Great as a pen cover or pen sheath as a gift!

For those of you who own fountain pens, how do you carry them around? One bottle? A cushioned pencil case? Or a roll pencil case? I used to use it in a case, but every time I wrote, I had to unscrew the flip, take it out, and close the flip again, which became a chore, so I started carrying it around bare.

You might think that I'm bothered by that kind of thing, but if it doesn't come out right away when I want to write, I'm done with it (lol) Having said that, I still don't care about scratches. Just when I was thinking, ``dünn one pencover'' was released. dünn is a series of leather products made using genuine leather that has been skimmed down to 0.5mm, and the one pen cover is also made from this ultra-thin leather. This suited me, a lazy person, very well.

What is noteworthy is how thin it is. This can be said about the entire dünn series, but it's already extremely thin. However, it is light. There is only 5g. Because it's so thin and light, it fits the pen perfectly and doesn't add any more bulk than necessary.

It looks like a pen dressed up.

The slits at each end have different lengths. The photo on the left is 10mm, and the photo on the right is 20mm.

The 10mm fits pens with the pen clip at the top of the cap, and the 20mm fits pens with the pen clip slightly below the cap.

You can choose according to the clip position of your fountain pen. As you continue to use it, the tight slit will curve inward, improving the fit.

I usually keep it in my pencil case.

It feels almost the same as storing a single pen in a normal pencil case. I used it on the go and didn't have time to store it in my pencil case! Even in such a case, as long as you attach the one pen cover, you can throw it into your bag without hesitation. By the way, the product I use together is "dünn passport & pencase."

No need to open or close! Just pull it out when you want to use it, and just insert it when you want to put it away!

I'm only saying what I saw when I saw it, but just by eliminating the two movements of opening and closing, my hurdle to using a fountain pen has lowered significantly. Also, since it is this thin, I am happy that I can pass the clip part through it. If I get stuck here, I get really annoyed (lol)

I was able to meet some users of dünn one pencover at the Techoken off-line meeting the other day, so I tried out the usability of the dünn one pencover by putting it in various fountain pens. Please use this as a guide. In any case, with the help of both of you, I personally have a large collection...it's amazing.

He usually carries this fountain pen in his bag. The ring part of the cap is raised, so there is a mold on the main body. However, since it is made of genuine leather, it fits snugly.

It's a very thick pelican. I was worried at first, but I was able to store it smoothly. When you hold it, it feels like a cigar.

This was completely impossible.

This is my personal property. It was originally made to hold this M400, so it can be stored comfortably.

A popular see-through skeleton model. There is some bulge on the ring part, but it is not a problem.

This ring is more flat, so it goes in very smoothly.

The ring is exciting because it is the model that Nagasawa's fountain pens were based on.

There is no problem here either.

Personally, this capless design is the one that suits me best. It fits perfectly into the deep notch. Since it is a functional fountain pen and a functional pen cover, it may be a good match.

There is no problem here either.

The clip on the hoodie is so distinctive, so it's nice to be able to display it and store it away. It feels good.

No problem.

It also goes in smoothly.

If you are buying a high-quality fountain pen for the first time, you may want to put it in your suit or jacket pocket and take it out for various uses, but you may also be very concerned about scratches on its surface. This happened to me myself, and in order to prevent this, I made a tube of dünn leather and covered it over my M400, which led to the birth of the dünn one pencover. When I start using high-quality fountain pens, I feel really relaxed.

I'm a super beginner, and my handwriting is a little messy, but it's a very important tool that makes me appreciate handwriting and creates a rhythm in my daily life. Fountain pens write smoothly, so if you get used to it, even the trendy low-viscosity ballpoint pens will feel heavy. I sincerely hope that by using dünn one pencover, more people will be able to carry their fountain pens with them casually but with care. https://dunnleather.com/products/dop/
